Order of operations matters when using computed properties and a formatter

[davisg123]

Specifying the computed property dependency before a number formatter and the | call results in the property not being recomputed

The idea of call formatter is to send arguments to function. The function will work with the arguements instead of getting the data in the model. With arguments Rivets will be able to bind all necessary data. You won't have to use the computed properties notation.
In your example this will be

In fact, the only usage of computed properties is
state.remainingTime < state.currentTime | call | formatter
In the following expression
state.remainingTime | call | formatter < state.currentTime
< and state.currentTime are handled as parameters for the formatter, not as computed properties. So it works because when state.currentTime changes, rivets will reexecute the expression.
In the correct notation in fact it works, but since 0.9 functions are not executed so when reevaluating the state.remaingTime it will return the same function as a pointer. The dataBinding won't be executed because the value (pointer on function) has not changed. See #572 it's the same problem here.
The good news is, when PR mikeric/sightglass#16 is merged, the bug will be fixed !

@jccazeaux mikeric/sightglass#16 is merged, but I'm not sure how to release.

[benadamstyles]

Should we change the docs on computed properties to make it clear that it doesn't need to be used if you are using | call?

[jccazeaux]

To release sightglass it must be pushed in npm as a 0.2.6. Then in rivets' package.json just reference this 0.2.6 before the build.
Yes the doc must be updated, i'll handle it with 0.9.2 update

[benadamstyles]

It is also on bower and component – shall we just ignore them?

[jccazeaux]

We should keep the version up to date in all the repo. Is sightglass really used outside rivets?

[benadamstyles]

I use it outside rivets 😛

[jccazeaux]

@Leeds-eBooks has sightglass been published?

[benadamstyles]

No, will do it asap

[jccazeaux]

OK, package.json must be updated to use it for the rivets.bundle.min.js?

[benadamstyles]

Yeah I guess I'll have to publish 0.9.4 after I've released sightglass?

[benadamstyles]

Ah, totally didn't know that bower fetches the latest version from github automatically!

[benadamstyles]

Ok updated sightglass is bundled in 0.9.4
